dc.description.abstractGastric mucosa of an elasmobranch species was examined by EM. The gastric glands contain 1 form of cell whose fine structure is similar to the cell that secretes HCl and pepsinogen of the amphibian gastric glands proper. These oxynticopeptic cells are characterized by a luminal surface with long projections of cytoplasm having dilatations in their thickness, a tubulo-vesicular system in the apical cytoplasm, a great number of mitochondria, some of which are of great length, a well developed granular endoplasmic reticulum and a conspicuous Golgi apparatus, and a large nucleus with a conspicuous nucleolus. A 4th part of the cells are binucleated. Physiological implications of some of these ultrastructural features are discussed.
